Managing a Headless VirtualBox Installation with phpvirtualbox (Ubuntu 16.04 LTS)
Phpvirtualbox is a web-based VirtualBox front-end written in PHP that allows you to access and control remote VirtualBox instances. It tries to resemble the VirtualBox GUI as much as possible to make work with it as easy as possible. It is a nice replacement for the VirtualBox GUI if you run VirtualBox in headless servers (like in the tutorial VBoxHeadless – Running Virtual Machines with VirtualBox 5.1 on a headless Ubuntu 16.04 LTS Server).
